Geostatistics & KrigingFrom scattered samples to a continuous surface.
Fit a variogram automatically, krige, and cross-validate in a few steps. Vesta selects the right forward and back-transforms for logratios and indicators and applies them for you.
Kriged soil organic carbon · one Ontario field
Every major kriging familyStandard, indicator, compositional and spatio-temporal kriging, plus co-kriging with a linear model of coregionalization.
Variograms without the fiddlingAutomatic fitting with an interactive editor when you want control over nugget, sill and range.
Uncertainty you can showKriging variance and exceedance-probability maps sit next to the estimate.
Cross-validation built inLeave-one-out diagnostics tell you how much to trust the surface before you publish it.

Exposure & contamination mappingInterpolate contaminant levels from monitoring sites into a continuous surface, and map the probability of exceeding a regulatory threshold alongside every estimate.Site & resource assessmentModel grade, soil properties or contamination across a site from your drill-hole or core samples, with co-kriging for a correlated variable and logratio variograms for compositional data.Sampling designUse the variogram range and the uncertainty map to see where your current samples leave the most uncertainty, and plan new locations there.
